P4300 G2 node upgrade failed

We have a 4 node P4300 G2 SAN with 3 of the nodes running Software Version 11.5.00.0673.0 but one of the nodes somehow failed during the upgrade process and is stuck at 10.5.00.0149.0. Everytime I try to "Check for Upgrades", I get an error connectiong to the FTP server. If I select Use Local Media, the whole process crashes due to the follow message: The storage system "10.1.3.100" running a manager has disconnected. The management group TCP connection timed out after 60 seconds. You will be logged out.

Aside from running a recovery on the one node, is there any other way of upgrading the software on this? Thanks!
